IDABEL, Okla. (AP) — A judge in Oklahoma has sentenced a former Southern Arkansas University rodeo team member to 42 months in prison for stealing horses from the school stables in Magnolia.

Jaci Jackson was also sentenced Monday to seven years of probation for her role in the theft of horses and equipment in 2011. The horses were discovered in Oklahoma — including one that had been killed — and Jackson faced charges in both states. She’s set to be sentenced in Arkansas on Feb. 6 for the theft.

Last August, Jackson pleaded guilty in Oklahoma to conspiracy to commit theft, bringing stolen property across state lines, knowingly concealing stolen property and cruelty to animals.

“It was a foolish act. It’s sad and tragic for Jaci’s family and for all the victims who owned the horses,” District Attorney Mark Matloff said.

Special District Judge Gary Brock agreed that the theft was instigated by Jackson’s mother, Wendi Cox, who is serving a 60-year prison sentence after she was convicted by a jury in Arkansas. But the judge noted that Jackson participated in the crime and attempted cover-up, even if she wasn’t the one who cut the throat of the horse named Credit Card.

“The statement by Jackson about the death of Credit Card was callous indifference when she told the joke about ‘What do you do with a credit card? You cut it up and throw it away,”’ Brock said.

Prosecutors alleged that the theft came about after a dispute between Jackson and fellow students at the school in Magnolia.

“After conspiring to avenge the alleged wrongs done to her, which were ridiculous accusations and proven to be false, Jaci Jackson committed the ultimate act of betrayal by stealing the most precious asset of her fellow rodeo teammates — their horses,” Matloff said.
